Integrating RHEL and Active Directory

I'm integrating RHEL 6.5 server and Windows Server 2008 R2 (Active Directory) for authentication. i.e Clients are able to login into RHEL serve using user details in AD.

I followed same procedure(Configuration 3) http://www.redhat.com/en/files/resources/en-rhel-intergrating-rhel-6-active-directory.pdf and https://www.youtube.com/watch?v=LEhz5ZVfYJI&index=16&list=WL

I configured same and it was not working as expected.

I'm getting a error like 

debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password
debug1: Next authentication method: gssapi-keyex
debug1: No valid Key exchange context
debug1: Next authentication method: gssapi-with-mic
debug1: Unspecified GSS failure.  Minor code may provide more information
Server not found in Kerberos database

debug1: Unspecified GSS failure.  Minor code may provide more information
Server not found in Kerberos database

debug1: Unspecified GSS failure.  Minor code may provide more information

Could you help me on this?

From Microsoft TechNet's Troubleshooting Tips:

DNS-related Error Messages

Investigate DNS issues if you are experiencing error messages similar to those listed as follows:

  • Host name cannot be canonicalized.
  • Incorrect net address.
  • Server not found in Kerberos database.
  • Cannot contact KDC for requested realm.

In me case the issue was that I had to use the FQDN, which is required by Kerberos. Not using a FQDN got me the same error, "Server not found in Kerberos database".

Also it's a good idea to double check that the DNS is resolving correctly and the server is reachable.
